with rolling admissions, then you will want your application in ASAP. i'm not familiar with the term "early admissions", but heres how rolling admissions works:
when a school starts taking applications, they have a set number of seats...lets say 30. you want your application there first so they dont have a bunch of other applicants to compare to. once they are down to 8 seats, they have seen the spread of applicants and have chosen who they think is best. every year it gets more competetive, and the ones they have chosen are likely to be pretty good. you would rather be in there early before they know how awesome thier applicants are. they wont be quite as picky early on as they will later. when you have few seats left, you are less likely to fill them with folks with poor stats. rarity makes things more valuable. so thats why you want to get your stuff in earlier vs later. find out if they do rolling admissions. on the other hand, if they dont, then the wait until a certain date and look through all of the applications, then make decisions. even then, it can be good to get stuff in early, but its not as critical.
i'm aware what courses constitute curriculum for a med tech program, and each of those subjects are actually clinical courses... you have taken clinical hematology, clinical microbiology, etc. good classes, but they have an emphasis for the clinical setting under the auspices of medical technology. undergrads cant just walk into those courses without being in a medtech program. that distinction could matter to some folks, but most might not notice.
i held a biology degree before i got my med tech degree, so i really dont know much about how not having a bio degree plays into things with PA schools. to get into my med tech program, a bio degree was a prerequisite. as a result, i would assume that someone with a bio degree would have more of a broad understanding of sciences than just a med tech degree, but id be speculating. i dont know that it really matters to have one over the other if you dont spend any time in the field. thats where the med tech training will help you stand out like you want it to. just having it on paper without experience means you have the title to a car but have never driven it.
having 2 C's thusfar is 1/3 of your medtech coursework. B's dont really say anything. you need to finish out your program with A's. i've discovered that PA school applications are an A quality game. B's are neutral (which isnt compelling for people to see), and C's should be an anomoly.
whether or not a med tech degree helps you stand out has to do with how you do in the program. id rather have better grades and just a biology degree than regular grades and a med tech degree. for me, it was handy to add a lot of the science coursework to my gpa because i did well in medtech. additionally, it provided an avenue for me to hold a position of responsibility in health care, so i was able to base a lot of my appeal to schools on that experience. if you are the person i recognize posting at the PA forums, then it sounds like you have some hands on experience at a clinic? thats actually good experience vs working in the basement of a teaching hospital.
the med tech degree in the application process is really what you make of it. it wont distinguish you any more than anything else unless you put it to work.
